Acronis do indeed have a solution called True Image and True Image Home. This is extremely easy to use and from the wording of the query (and an infered level of expertise as a result) is probably your best solution.
Check licensing carefully as although it is possible to clone multiple machines using one media (buying physical copies give you a bootable CD), if I recall correctly you should have one copy for each machine you are cloning. Volume licence may be available.
The key thing to remember is the hardware should be identical, or at least use the same drivers, or your imaged machines won't work.
Some solutions also require all computers to have the same hard drive size, others will work if the hard drive to be cloned to is the same size or larger than the machine you captured the image from.
Cloning Solutions include-
Acronis True Image
CloneZilla (free)
Symantec Ghost
Automated Windows Deployment Solutions include-
Answer file installation
RIS (depreciated, and requires software to be installed afterwards)
Windows Automated Installation Kit (Windows Vista and above)
Clonezilla is fairly easy to use with the Live CD if you have technical knowledge and is free but Acronis definetely the easier to use.
When Cloning machines all software and configuration (including user accounts and temporary files etc.) will be copied to the new machine. This should be done while the machine is NOT part of a domain as domain SSIDs must be unique- join your computers to the domain afterwards. As the machine SSID will not be unique you should be aware that WSUS will only report for one computer per image. Ideally you should build a new clean configuration for deployment.
Automated deployment saves clicking through the setup screens and entering the licence key each time for Windows, but you'll still have to install software on top. In many cases this can be done in Active Directory but this seems beyond the scope of your expertise.
